A memory trace is like a faint line etched into your brain by an experience. It's the physical or chemical change representing the memory. Imagine it as the digital footprint of a thought or event. Each time you recall something, you're essentially retracing that line, strengthening it. Without regular retracing, the trace fades, like an old path overgrown with weeds. A memory trace is not the memory itself, but rather the *potential* for recall.
